概括
这一系统性审查比较了开放式 (OF) 和无 (FL) 的美学冠状延长 (ECL) 手术,用于过度的牙显示 (EGD). 虽然FL在探测时显示出减少的出血,但这两种技术都产生了可比的结果,FL与牙边缘的不利变化有关.
科学领域:
- 牙周病学 牙周病学
- 审美牙科 审美牙科
- 在口腔外科手术.
背景情况:
- 过度的牙显示 (EGD) 对微笑美学产生负面影响.
- 审美冠状延长 (ECL) 手术是EGD的主要治疗方法.
- 开放式 (OF) 和无 (FL) ECL技术之间的选择仍在争论中.
研究的目的:
- 在EGD的ECL手术中系统地审查和比较OF与FL技术的临床结果.
- 为了评估牙边缘变化,探针出血,探针深度,临床附着水平和角质化牙高度的差异.
主要方法:
- 随机对照试验 (RCT) 的系统审查和元分析.
- 在PubMed,Cochrane CENTRAL,Scopus和Web of Science中搜索相关的RCT.
- 包括五项与180名患者的RCT,比较了OF和FL ECL技术.
- 分析了主要结果 (相对牙边缘变化) 和次要结果 (探测时出血,探测深度等). 使用标准化的平均差异.
主要成果:
- 与OF相比,微创FL技术显示了相对牙边缘变化的显著减少 (SMD = -0.38,P < 0.001).
- 与OF (SMD = -0.63,P = 0.04) 相比,FL技术也显示了探测时出血的显著减少.
- 对于其他结果没有观察到任何显著差异,这表明FL和OF技术之间的结果总体上是可比的.
结论:
- 与开放技术相比,最少侵入性的无 ECL 手术可能会导致较不有利的相对牙边缘结果,用于治疗过度的牙显示.
- 在ECL手术中,FL和OF技术在大多数临床结果中都显示出可比的结果.
- 需要进一步的大规模RCT来验证这些发现.

Random Sampling Method
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...
Random and Systematic Errors
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...
Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Wald-Wolfowitz Runs Test II
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...
